ThanX for all the feedback and info. I still didn't find much info online as I thought I should. I also saw it was not a BB so thanks for confirming what I read dgc333. So with that said I'm not sure if I will go through with even picking it up or not. I think the heads will fit on my 360 so maybe I can do some porting and get more flow? Any of you know if I could do this or any advantages from these heads?
